Product Summary

Valve springs are one of the most critical and most overlooked components in your engine. Proper selection of the valve spring begins with identifying the application and selecting all of the valve train components to achieve the engine builders’ goals. Most valve springs come with a protective coating to resist corrosion, if this becomes scratched it will become a weak spot and expose the spring to stress failure. Keep the engine speed down until the engine oil (not water) reaches the operating temperature and take it easy for the first few hundred miles.

The spring is selected to complement the system and must be matched with the entire valve train in order for the engine to reach its full potential. It does absolutely no good to install a cam that will rpm to 8000 if you do not have the correct springs. Improper selection of the wrong valve spring is one of the most common causes of engine failure.

Valve springs are shipped with a rust preventative coating that should remain on the spring throughout engine assembly. Do not clean springs with acidic or evaporative cleaners. This causes rapid drying and promotes the formation of rust on the surface, which can cause catastrophic failures. Valve spring retainers are also an important part of the tuning equation. TorqueCars would advise never to fit new springs with old retainers.
